The Inertial Measurement Unit (IMU) is widely used in the monitoring of mining assets. A good example Polish underground copper ore mines KGHM, where research work with use IMU has been carried out for several years. potential inertial sensors was ensured by development advanced analytics using machine learning methods to support maintenance management an extensive park and manufacturer adaptin...

Since two decades ago with the increase in dam construction projects in Iran, a major part of the ancient and historic sites of the country went under water. As mostly, do not exist desirable and sufficient relationship between Iranian Cultural Heritage, Handicraft and Tourism Organization (ICHHTO) and other organizations like Ministry of Energy, the budget allocated to the study of ar­chae...

The site of Wonderwerk Cave, located in the Northern Cape Province between the towns of Danielskuil and Kuruman, preserves an extraordinary sequence that spans close to 2 million years of hominin activity (see Chazan and Horwitz, this volume, for an overview of the site). The earliest phases of occupation have only been recovered in Excavation 1 near the front of the cave in excavations carried...

The first step in mining activities is rock excavation in both mine development and production. Constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. Also, mechanical excavation and mining is more compatible with automation, meaning possibility of reduc...

Abstract Steel sheet pile walls are being widely used in civil engineering projects for support systems. Soil is not uniform in depth, sometimes may be exit loose or soft soil layer in various depth. This issue can cause different effects on ground surface displacements, forces and moments acting on sheet piles and struts during excavation procedure, compared with status that soil is uniform...

We report on a study carried out within the 3D MURALE project, in which the complete workflow necessary for automatic recording, reconstruction and interactive visualization of artefacts on archaeological excavation sites has been tested. With state-of-the-art technologies from digital photogrammetry, computer vision and computer graphics a prototypical pipeline for recording, 3D modeling and v...

In major construction projects involving extensive excavation and tunneling, it is crucial to have accurate realtime monitoring to ensure that support structures are not excessively stressed as these could lead to collapse and fatalities. The integration of machine-to-machine (M2M) technologies has been proposed to improve the process of transferring data from the sensors in the monitoring site...
